Hanger Project is of course one excellent option - but I have to say, with no disrespect to Kirby (this speaks well of his great business & marketing, in fact), that the prices have skyrocketed from the early days and there's at least an impression that they are less geared towards being an enthusiast's quality product and more a luxury-marketed option with the price and profit to match.
If you look around, find some hangers from Beverly Coat Hangers - they are the firm that made Hanger Project's hangers at first, and they make very nice stuff. Oxxford uses them, as do H. Freeman & Son and many other high-end makers who still use wooden hangers. http://www.beverlyhanger.com
is their website, though they don't do direct sales off that. Check out Amazon and Ebay from time to time - you can find surprisingly good deals. Just since they're usually unbranded, you can pay for six or twelve of those hangers what you might pay for one or two of the, say, Oxxford or Hanger Project branded hangers - only you're getting the same hanger without the label!
